A dual fluid spray nozzle (20) adapted to produce a finely atomized spray of a liquid includes a body (30) which encloses a first atomization chamber (36, 36'), a nozzle tip (70, 70'), and a plate (60, 60', 60") disposed between the first atomization chamber and the nozzle tip so a to define a second atomization chamber (55, 55'). The plate defines a plurality of passages (61, 61', 61") through which liquid passes from the first atomization chamber into the second atomization chamber and is further atomized. The nozzle may include a plurality of plates (60', 60"; 80', 80") and more than two atomization chambers (36', 36", 55'). In such embodiments, each plate has a reduced total cross-sectional area of passages relative to the preceding plate.
Buses doubles de vaporisation (20) conçues pour produire un flux finement atomisé et comportant un corps (30) englobant une première chambre d'atomisation (36, 36'), une extrémité de buse (70, 70') et une plaque (60, 60', 60'') placée entre la première chambre d'atomisation et la plaque de manière à former une deuxième chambre d'atomisation (55, 55'). La plaque comporte une série de passages (61, 61', 61'') par lesquels le liquide passe de la première chambre dans la deuxième avant d'être atomisé. La buse peut comporter plusieurs plaques (60, 60', 80, 80') et plus de deux chambres d'atomisation (36', 36'', 55'). Dans ces variantes, chacune des plaques présente une section droite totale inférieure à celle de la précédente.
